Explicit support for matching cancellation tokens with It class. (It.IsCancellationToken())

• [x] Feature request

Describe the feature

When mocking async methods that require a cancellation token you can use It.IsAny<CancellationToken>() syntax like this:

myMock.Setup(m => m.DoSomethingAsync(It.IsAny<CancellationToken>()));

I propose adding a new method to It class for matching cancellation tokens, that does exactly the same:

myMock.Setup(m => m.DoSomethingAsync(It.IsCancellationToken()));

Rationale:

• It's slightly more readable and less verbose than It.IsAny<> syntax.. Readable code is good 👍
• Async methods are extremely common and mocking them is common as well.
• It's purely syntactic sugar. It breaks nothing.
• Code completion will be easier. Right now you need to do it in two steps (IsAny + CancellationToken in generic params).
• It class is static, so you cannot add an extension method with similar behaviour on your own.
